DYEIN G APPARATUS.

Specification of Letters Patent.

Patented Sept. 26, 1911.

To all whom it may concern:

Be it known that I, VILLIAM R. SMITH, of Buffalo, in the county of Erieand State of New York, have invented certain new and useful Improvementsin Dyeing Apparatus, of which the following is a specification.

This invention has for its object to provide a simple and effectiveapparatus for dyeing fibrous materials of various kinds,

and particularly fibrous material in the form of yarns or threads,contained in a receptacle which is immersed in a body of dye liquor.

The invention is embodied in an apparatus in which the inclosed fibrousmaterial to be dyed is subjected to contact withthe dye liquor, not onlyby being submerged therein, but also by being rotated while submerged inthe liquor, the rotation of the body of fibrous material to be dyedbeing caused by movement of the liquor in a tank or reservoir.

The invention consists in the improvements which I will now proceed todescribe and claim.

Of the accompanying drawings z-Figure 1 represents a top plan view of adyeing` apparatus embodying my invention; and Fig. 2 represents asection on line 2-2 of Fig. l.

Similar reference characters indicate the same or similar parts in allthe figures.

In the drawings, 12 represents a horizontal endless tank composed of abottom 12, an outer curb 12b, and an inner curb 12C, the said curbsbeing endless and preferably in the form of flattened ellipses so thatthey form an endless horizontal passage of substantially elliptical formin which the body of dye liquor may be confined and circulated. Meansare provided for circulating the dye liquor, said means, as here shown,comprising two paddle wheels 13, the shafts 14: of which extend acrossthe relatively straight portions of the tank, and are provided withbevel gears 15 meshing with a bevel gear 16 on a driving shaft 17.

The described mechanism is adapted to rotate the paddle wheelssimultaneously in opposite directions and thus cause a continuouscirculation of dye -liquor in the tank, as indicated by arrows in Fig.1.

18,18 represent cylindrical rot-ary baskets adapted to contain thematerial to be dyed, and made of open Work material such as Woven wireor perforated sheet metal, so

that the liquor may pass freely through the basket-s and the materialcontained therein. Each basket is adapted to rotate on a vertical axis19 supported at its lower end by the bottom of the tank and engaged atits upper end with a suitable bearing on a cross bar 20, which may beremovably connected with the tank to permit the removal of the basket.Each basket is preferably of annular form, the inner side of its storagespace being formed by a perforated wall 18 which is concentric with theouter wall. The basket may be removably mounted on the axis 19, or itmay be suitably engaged therewith and filled and emptied without removalfrom the tank, a suitable removable cover being provided.

The baskets are entirely submerged in the body of dye liquor, and arerotatable by the movement of the liquor in the tank so that all sides ofeach basket are presented to the advancing stream of liquor. In theconstruction here shown the rotation of the baskets is due primarily tothe fact that the axis of each basket is located nearer the inner curb12c than the outer curb 12b so that there is a relatively wide spacebetween the outer side of the basket and the outer curb. The moving bodyof liquor therefore exerts a greater pressure on the outer side of thebasket than on the inner side, and thus causes the rotation of thebasket.

The baskets are preferably located in the abruptly curved portions ofthe tank, as shown by Fig. l, so that the liquor flowing along therelatively straight portions of the tank is deflected by the curvedportions of the outer curb. against the outer sides of the basket, thusincreasing the speed of rotation of the basket beyond that which itwould have if the basket were located in a relatively straight portionof the tank.

When the described apparatus is used for dyeing wool, the material maybe in the form of sliver disposed in tops or cheeses and placed in thebaskets. It is obvious, however, that fibrous material of any kind andin any form may be dyed by the apparatus.

It is obvious that the tank may be provided with one or more baskets,and that when the tank is of elliptical form as shown, each of theabruptly curved portions may have one or more baskets.

Y Copies of this patent may be obtained for The location of the axis ofthe basket nearer one side of the tank than the opposite side Would besuficient to cause the rotation of the basket by the moving liquid it'the basket were located in a relatively straight portion of the tank.YThe deflection of the moving liquid by the outer side of the abruptlycurved portion of an elliptical tank, Will cause the rotation of abasket located in said portion, Whether the axis of the basket belocated nearer one side than the other or equidistant from said sides.

l. An apparatus of the character stated comprising an endless horizontaltank, means for moving liquid horizontally therein, and a basket mountedto rotate on a substantially vertical axis in the tank and rotatable bythe movement of the liquid therein. y

2. An apparatus of the character stated comprising an endless horizontaltank, means for moving liquid horizontally therein, and a basket mountedto rotate on a substantially vertical axis in the tank, said axis beingnearer one side of the tank than the opposite side, whereby liquidmoving in the tank is caused to rotate the basket.

character stated substantially vertical axis in the tank, said tankhaving a substantially straight portion and an abruptly curved portion,and the basket being located in said curved portion, whereby liquidmoving in the tank is deflected against the outer side of the basket andcaused to rotate the latter. y

4. An apparatus of the character staten comprising an endless horizontaltank, means for moving liquid horizontally therein, and a basket mountedto rotate on a substantially vertical axis in the tank, said axis beingnearer one side of the tank than the opposite side, and the tank beingformed with a substantially straight portion, and

with an abruptly curved the basket is located.

In testimony whereof I have affixed my signature, in presence of tivoWitnesses.
